H12-1000 Vertical Wind Turbine — 1000 W at 12 m/s, 48 V

Built for wind that never blows straight.

Around buildings, trees and ridgelines, wind does not arrive as a clean steady stream — it swirls, gusts and swaps direction by the minute. A conventional turbine spends half its life hunting back and forth trying to face weather like that. Meanwhile the battery bank it was meant to feed keeps draining, and the generator gets another run.

The H12-1000 is an H-type vertical axis wind turbine — five aluminium alloy blades standing upright around a central generator, with a printed rotor size of 1.28 m / 2 m. Because the rotor is vertical, it takes wind from any direction at all, with no yaw mechanism to swing, hunt or wear: the manufacturer calls it 360° auto windward. One thing about the photos: the domed centre rotor shown between the blades in some pictures is an auxiliary starting rotor — an optional extra at additional cost, not part of the standard unit. It starts working in a 2 m/s breath of wind and suits exactly the turbulent, variable-direction sites — rooftops, yards, built-up blocks — that frustrate a horizontal machine.

Straight up about the numbers: the 1000 W rating is measured at 12 m/s — a 43 km/h wind, not a normal afternoon breeze. The manufacturer publishes no power curve for any of its vertical-axis machines, so we cannot show you an output table for this one. We could calculate one and present it as measured — plenty of sellers do exactly that — but we would rather tell you it is missing. What the maker does publish: 1000 W at 12 m/s, a maximum of 1,100 W, and charging from a 2 m/s start. On a normal usable breeze expect a fraction of the rated figure, working around the clock. Treat it as a charging assist for your solar, not a replacement for it.

What It Solves

• The swirling rooftop wind: buildings chop wind into gusts from every direction. A vertical rotor does not care where the wind comes from — there is nothing to turn, so nothing is wasted turning.
• The overnight drain: the fridge and the lights pull amps all night while the panels do nothing. Wind keeps feeding the bank while you sleep.
• The grey winter week: the fronts that flatten your solar for days are exactly the weather this machine works hardest in.
• The close-neighbours problem: the maker pitches this design at urban rooftops, homes and street lighting for a reason — a slow-turning vertical rotor with no yaw gear is an easier machine to live beside.
• The gear nobody visits: telecom sites, street lighting, monitoring gear on a back block — steady small loads a long way from a powerpoint.

Key Features

• Takes wind from any direction: 360° auto windward — no yaw mechanism to hunt in shifting gusts or wear out.
• Five-blade H-type rotor: aluminium alloy blades on an aluminium alloy body, printed rotor size 1.28 m / 2 m.
• Starts early: the maker publishes a single combined start-up / cut-in figure of 2 m/s (7.2 km/h).
• Built to survive 45 m/s: that is 162 km/h. If your site regularly sees worse, this is the wrong machine for it and we would rather say so.
• Permanent magnet generator: 3-phase AC synchronous with NdFeB magnets, IP54 protected — no brushes to wear.
• Two layers of protection: electromagnetic brake for overspeed, controller over-current protection plus dump load for overload.
• 48 V system: made for a 48 V battery bank — the voltage most serious off-grid banks now run.
• Two controller choices: the HCM wind-solar hybrid (runs panels too) or the pure-wind WW10-48-48 MPPT from the MWM series — pick either as a kit, or take the turbine only.

Kit, Or Turbine Only

The hybrid kit pairs the turbine with the manufacturer's matched wind-solar hybrid controller, the LHCM1-06/48V. The hybrid part matters: wind charges through MPPT, and the same box takes a solar array on a PWM input — one controller runs both, which is how most people end up wiring these anyway. One honest caveat: the manufacturer publishes only series-level figures for this controller, not model-level ones — which is why there is no LHCM spec table on this page.

Never going to run solar? Pick With Pure-Wind Controller and the kit ships the manufacturer's pure-wind MPPT unit instead — the WW10-48-48 — the heavier-duty unit from the manufacturer’s MWM series, and the one the manufacturer now recommends for this turbine. Wind only, no PV input at all — full details in the Specs tab.

Already have a controller rated for this turbine? Pick Turbine only.

What Else You'll Need

A turbine on a pole is half a system. The other half is a mast in clean air, cable sized for the run, breakers and an isolator, a dump load (included with the kit controllers) and a battery bank to feed. Cable sizing depends on run length, voltage and current — that is your electrician's call, not a line on a product page. Browse bus bars, breakers and wiring in the Electrical Supplies collection, and the full controller range here.

Representative photos: the manufacturer supplies one set of photographs per turbine family, not per model. The H12-1000 you receive is this five-blade design, at the sizes in the spec table.

Limits

It is not 24/7 power. It makes power when the wind blows and none when it drops. Wind supplements solar here, it does not replace it — keep the panels and size the bank properly.

The 1000 W rating needs a 43 km/h wind. That is the manufacturer’s figure at 12 m/s, with a published maximum of 1,100 W. On the light breeze most sites see for most of the year you will get a fraction of it, working around the clock.

There is no power curve for this machine. The manufacturer publishes no wind-speed output table for any of its vertical-axis turbines, so we cannot show you what it makes at 5 to 7 m/s. We could calculate one and print it as measured — plenty of sellers do — but we would rather tell you it is missing.

It is built to survive 45 m/s (162 km/h). If your site regularly sees worse than that, this is the wrong machine for it and we would rather say so than sell you one.

The auxiliary starting rotor in some photos is an optional extra. The domed centre drum shown between the blades costs extra and is not part of the standard unit.

It is not plug-and-play. The turbine weighs 75 kg before the mast, so have your installer confirm any rooftop structure can carry it. Professional installation by a licensed electrician is a warranty condition — keep the invoice — and the manufacturer treats blade damage from consistently extreme wind, and motor burnout after prolonged high-speed running, as case-by-case assessments rather than automatic cover.

Q & A

Will it really make 1000 watts?

At 12 m/s — a 43 km/h wind — that is the manufacturer's rating, with a published maximum of 1,100 W. On a normal usable breeze you will see a fraction of that, working day and night. The manufacturer publishes no power curve for its vertical machines, so we will not print an output table we cannot source — size your expectations conservatively, and treat the machine as an around-the-clock assist for your solar.

Why a vertical axis turbine instead of a normal one?

A horizontal turbine must face the wind, so on a turbulent site it spends its time swinging back and forth chasing gusts. An H-type vertical rotor takes wind from any direction without moving anything — no yaw mechanism, nothing to hunt, nothing to wear. In clean, steady, open-country wind a horizontal machine of the same rating is usually the better harvester; in the chopped-up wind around buildings and obstacles, the vertical layout earns its keep. If your site is open and laminar, look at our L-series horizontals instead — honestly.

Does the kit controller take solar panels?

The hybrid option does. The LHCM1-06/48V runs the turbine through MPPT and takes a solar array on a PWM input — one unit, both sources. The pure-wind WW10-48-48 has no PV input at all. Pick the package that matches how you will actually wire the system.

Why don't you publish a charging current in amps?

The supplier publishes no battery-side charging current for either controller offered with this turbine, and we will not calculate one by dividing watts by volts — that is how people end up sizing breakers off a guess. The WW10-48-48’s own manual does print 21 A rated input current, and that figure is in its table below. Do not size cable or breakers from the wattage in any product title.

Is the cable from the turbine AC or DC?

AC. The turbine generates 3-phase AC, and the rectifier inside the controller converts it to DC to charge the battery. A generator is not a battery: the voltage on that cable rises with rotor speed, which is exactly why the matched controller is built to take far more than the nominal battery voltage on its input. Cable selection and protection are your electrician's job.

Can I mount it on the roof?

Yes — the maker rates it for 3 to 6 m above the roofline, or 6 to 10 m on a ground mast. Two things to weigh up: height is output, because turbulence near buildings eats the wind before the blades see it; and this machine weighs 75 kg before the mast, so have your installer confirm the structure can carry it.

What happens to it in a storm?

The electromagnetic brake and the controller's overspeed protection wind it back, and the machine is built to survive 45 m/s (162 km/h). If your site regularly sees more than that, do not put this turbine on it.

What is the warranty position?

Twelve months. Professional installation by a licensed electrician is a condition of it — keep the electrician's invoice with your paperwork. Be aware the manufacturer treats blade damage from consistently extreme wind, and motor burnout after prolonged high-speed running, as case-by-case assessments rather than automatic cover.

How long until it arrives?

Built to order and sea-freighted — allow 4 to 6 weeks (up to 7 for WA and regional addresses). Delivery to Australia is priced to your door by postcode — put your postcode in above to see the sea and air prices. New Zealand delivery is still included. Need it faster? Pick air freight at checkout and it will land in around 2 to 3 weeks. The turbine ships as two boxes — the longer one is just over 2 m — and the kit controller adds its own carton.
